Despite Colts owner Jim Irsay suggesting that Andrew Luck could return to the field from a lacerated kidney this week, there is still some uncertainty surrounding when the quarterback will return and even some doubts as to if he'll return this season, reports ESPN’s Adam Schefter.

Luck sustained the injury to his kidney in addition to a partial tear in an abdominal muscle during the Colts’ 27–24 victory over the Denver Broncos on Nov. 8. He was expected to miss two to six weeks.

Luck has played in just seven games this season, having missed two games earlier in the season with a shoulder injury.

He was ruled out of Sunday’s game against the Jacksonville Jaguars. The Colts lost 51–16, dropping to 6–7.

To make matters worse for the Colts, quarterback Matt Hasselbeck was seen leaving the stadium on Sunday night with his left arm in a sling, reports Shefter.
